AT&T and T-Mobile are having a fast-draw shootout in the old Texas style in Dallas, as both carriers pump up their HSPA networks to super-high speeds. T-Mobile won the crown thanks to their growing HSPA+ network. In four of the ten locations tested by Staff Editor Sean Ludwig, T-Mobile scored over 5 megabits, which pushed them past AT&T on overall speed. More towers would have widened the gap further.

Sprint, meanwhile, needs to work on their WiMAX in Dallas. Poor signal quality in our testing locations led to dropouts and slow speed results which were bested by two 3G carriers.
